EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 611,097, dated September 20, 1898.

Application filed February 4, 896. Serial No. 578,058.

(No model.) Patented in Switzerland September 8,1893, No. 7,284;

To (tZZ whom it may concern:

Be it known that I, GEORG BAUM, a citizen of the Republic of Switzerland, and a resident of Rorschach, Switzerland, have invented certain new and useful Improvements in Embroidcling-Machines, (for which Letters Patent were granted to me in Switzerland, No. 7,284, dated September 8, 1893; in France, No. 232,861, dated September 16, 1893; in Germany, No. 76,353, dated September 19, 1893, and in England, No. 17,671, dated September 20, 1893,) of which the following is a specification.

Heretofore in embroidering small square pieces of fabric, such as pocket-handerchiefs, a separate frame for each piece has been used, which frames were fitted into the outer or main frame, and to facilitate the embroidering of the four edges of each piece of fabric after the first edge the said small frames had to be turned individually about ninety degrees in order to bring the four edges successively to the height required for the needles when embroidering.

This invention has for its object to reduce the number of small frames and the separate turns to be imparted thereto in such a manner that, for instance,when embroideringthe fabric or cloth for sixteen pieces three turns only are necessary for turning the whole of the fabric or cloth for the sixteen pieces in lieu of, as heretofore, three times sixteen, or forty-eight turns.

To this end the invention consists of a Swiss embroidering machine comprising two or more horizontal rows of needles, of an outer or main frame extending over the whole length of the machine, and quadrate fabricframes supported on said main frame and extending in vertical direction over the rows of needles, each of said fabric-frames carrying an undivided piece of fabric for a number of pieces equal to the square of the number of rows of needles employed, so that by only three turns of the fabric-frames all the four edges of a quadrate number of pieces are embroidered.

In the accompanying drawings, Figure 1 represents a detail elevation of a quadrate fabric-frame as attached to the main frame,

and Fig. 2 is a vertical transverse section of a Swiss embroidering-machine with four rows of needles and my improved fabric-frame.

The same reference-letters indicate corresponding parts in both the figures.

In the drawings,g is the outer or main frame, W91 07, 71 the four rows of embroidering-needles, and r a quadrate fabric-frame, of which three are supported by the main frame. The main frame g is equal in length with the length of the embroideringmachine, while the frame 7' extends over several rows of needles, preferably the whole height of the main frame, and which holds the undivided fabric or cloth not for one, but for a number of such pieces for the purpose of embroidering simultaneously a square number, (in the present instance sixteen.) The number of rows of needles n n n n, Fig. 2, correspond with the number of rows of pieces of fabric to be embroidered above each other on the fabricframe r-that is, sixteen pieces in four rows. As the said rows of needles move toward the fabric-frame they engage and embroider simultaneously the four rows of edges of all the pieces t upon the frames 0, after having had a turn of ninety degrees relative to the main frame imparted thereto presents first the edges II, on a second turn the edges III, and on a third and final turn the edges IV of all the pieces of fabric to the four rows of needles to be embroidered.

\Vith each fabric-frame described the cloth for a number of as yet undivided pieces of fabric (in the present instance sixteen) does take part in the turn of each fabric-framethat is, the manipulation hitherto necessary for the adjustment of each individual piece of fabric suffices for the simultaneous adj ustment of the said number, which results in a considerable saving of time and labor.

In adapting embroidering machines in practice for this invention two, three, four, or more rows of embroidery-needles may be employed above each other for the same fabric, in which case each fabric-frame must hold cloth for four, nine, or sixteen pieces, &c. that is, for a number of pieces equal to the square of the number of the rows of needles employed. The usual sizes of machines admit of inserting into the main frame g three fabric-frames side by side. The simultaneous embroidering of three times sixteen, or fortyeight, pieces is obtained. As each fabricframe after having embroidered one edge of each piece of the series of not yet divided pieces (four pieces in each of the three frames) must be turned three times, only nine quarter-turns are necessary. As three fabricframes are employed side by side in the main frame and as nine quarter-turns are necessary, whether the fabric-frame holds four, nine, or sixteen pieces, &c., the saving of time, owing to the reduction in the turns, will be greater in proportion to the increase of pieces upon one of the fabric-frames. In order to render the attention of the machine not too difficult, each fabric-frameis intended practically for a cloth for sixteen pieces only.

The fabric-frames are formed on their sides with teeth ,2, similar to the separate frames heretofore in use, and are inserted into the outer frame 9 by being slid into a groove formed at its bottom by sheet-metal strips 0, so as to be guided and abut sidewise against stops a and be secured at the top by means of clamps 75, adapted to turn on the wingscrews of the outer frame.

My improved fabric-frames, which might aptly be termed collective frames, are especially adapted for use in connection with the embroidering-machines, for which Letters Patent of the United States were granted to me on the 6th of June, 1893, No. 498,925, inasmuch as the same permits a greater-number of rows of needles than the ordinary embroidering-machines. In my aforesaid patent the machine is provided at its respective operative parts with a device for causing the undulatory folding of the embroideringthreads during the inward motion of the carriage-that is to say, with the device for preventing the too great sinking of the threadsand consists, briefly, in the provision of a number of movable supporting-frames which are operated by the reciprocating carriages, said frames resting sidewise on the frame of the machine, so that the supporting-frames form, as it were, a grid on which the threads are supported and which permits during the inward motion of the carriage a folding of the embroidering-threads only between the individual frames, and then in comparatively small loops only.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In an embroidering-machine, the combination of a plurality of embroidering mechanisms, the number of such mechanisms in each row corresponding with the number of rows thereof, and a square fabric-frame extending over all the embroidering mechanisms,whereby three turnings of the fabric-frame suffice for embroidering as many complete patterns as there are rows of embroidering mechanisms.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, this 21st day of December, 1895.
